After connecting interconnecting and supply wiring be sure to shape the cables so
that they do not put undue force on the electrical covers or panels. Install covers
over the wires. Incomplete cover installation may cause terminal overheating,
electrical shock, or fire.
(13)
If any refrigerant has leaked out during the installation work, ventilate the room.
(The refrigerant produces a toxic gas if exposed to flames.)
(14)
After all installation is complete, check to make sure that no refrigerant is leaking
out. (The refrigerant produces a toxic gas if exposed to flames.)
(15)
When installing or relocating the system, be sure to keep the refrigerant circuit
free from substances other than the specified refrigerant (R410A), such as air.
(Any presence of air or other foreign substance in the refrigerant circuit causes an
abnormal pressure rise or rupture, resulting in injury.)
(16)
During pump-down, stop the compressor before removing the refrigerant piping. If
the compressor is still running and the stop valve is open during pump-down, air
will be sucked in when the refrigerant piping is removed, causing abnormal
pressure in the freezer cycle which will lead to breakage and even injury.
(17)
During installation, attach the refrigerant piping securely before running the
compressor. If the compressor is not attached and the stop valve is open during
pump-down, air will be sucked in when the compressor is run, causing abnormal
pressure in the freezer cycle which will lead to breakage and even injury.
(18)
Be sure to establish an earth. Do not earth the unit to a utility pipe, arrester, or
telephone earth. Incomplete earth may cause electrical shock, or fire. A high surge
current from lightning or other sources may cause damage to the air conditioner.
(19)
Be sure to install an earth leakage breaker. Failure to install an earth leakage
breaker may result in electric shocks, or fire.
(20)
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction concerning use of the
appliance by a person responsible for their safety.
(21)
Children should be supervised to ensure that they do not play with the appliance.
(22)
If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid a hazard.
!
(1)
Do not install the air conditioner in a place where there is danger of exposure to
inflammable gas leakage. If the gas leaks and builds up around the unit, it may
catch fire.
(2)
Establish drain piping according to the instructions of this manual. Inadequate
piping may cause flooding.
(3)
Tighten the flare nut according to the specified method such as with a torque
wrench. If the flare nut is tightened too hard, the flare nut may crack after a long
time and cause refrigerant leakage.
